Countries should not stop using AstraZeneca’s Covid-19 vaccine over fears it causes blood clots as there is no indication this is true, the World Health Organization says.
Bulgaria, Denmark and Norway are among the countries that have paused its use.
But on Friday a WHO spokeswoman said there was no link between the jab and an increased risk of developing a clot.
Margaret Harris said it was an “excellent vaccine” and should continue to be used.
Around 5 million Europeans have already received the AstraZeneca jab.
There have been about 30 cases in Europe of “thromboembolic events” – or developing blood clots – after the vaccine was administered. There were also reports that a 50-year-old man had died in Italy after developing deep vein thrombosis (DVT).
The WHO is investigating the reports, as it does any safety questions, Ms Harris said.
On Friday, AstraZeneca said the recorded number of blood clots in vaccinated people was “significantly lower… than would be expected among the general population”.
“An analysis of our safety data of more than 10 million records has shown no evidence of an increased risk of pulmonary embolism or deep vein thrombosis,” a spokesperson said.
